5. Level the pump mounting pads:
NOTICE: Remove all dirt from the mounting pads in order to make sure that you achieve the
correct leveling. Failure to do so can result in equipment damage or decreased performance.
a) Put one machinist's level lengthwise on one of the two pads.
b) Put the other level across the center of the two pads.
c) Level the pads by adjusting the four jackscrews in the corners.
Make sure that the machinist's level readings are as close to zero as possible, both lengthwise and
across.

necessary.
The correct level measurement is a maximum of 0.002 in./ft (0.0167 mm/m).
Spring mounted installation
WARNING:
Springs can store energy that can launch parts at a high velocity. Before you perform any tasks, make sure
that all springs are positively locked against free expansion.
NOTICE: The spring-mounted baseplate is designed only to support piping loads from thermal
expansion. You must support the suction and discharge piping individually. Failure to do so may result in
equipment damage.
Determine which spring-mounted baseplate you are working with:
If... Then...
The springs are of equal lengths with some mounted
above the baseplate and some mounted below the
baseplate.
Complete the steps in Install the baseplate using
spring mounting (first generation).
The springs are of different lengths and mounted
below the baseplate.
Complete the steps in Install the baseplate using
spring mounting (second generation).
Install the baseplate using spring mounting (first generation)
Check these items before you start this procedure:
• All springs in the first-generation spring-mounted baseplate are identical and have the same spring
constant.
• The foundation pads are not provided with the baseplate. Make sure that the foundation pads are 316
stainless steel plates, which have a 63 to 125 micro-inch surface finish.
• Make sure that the foundation pads are correctly installed on the foundation/floor. See the
instructions from the manufacturer.
